Cotton is mainly harvested in monsoon season or fall. And it is planted in tropical and subtropical regions including the Americas, Africa and India. Cotton stalks are the wastes after cotton harvest with yield of about 200 kg in per acre. Raw materials are cheap and abundant with low use value, and are usually used as fuel by farmers. If we can use cotton stalks pellet machine to process them into particles, we will find that the value of these cotton stalks should never be ignored.
Value Contrast between Cotton Stalks and Cotton Stalks Pellets
A. Density of cotton stalks is generally about 110-130kg / m3, covering a great piece of area, and causing serious air pollution because of its low burning rate; while density of cotton stalks pellets is greater than 1100kg/ m3, extremely convenient to transport and store. At the same time, its combustion performance is greatly improved.
B. The volume of cotton stalks particles is 1/30~40 of cotton stalks and its relative density is 10 to 15 times of the raw materials. Calorific value is up to about 3400 to 6000 kcal. Cotton stalks particles are high cost-benefit solid fuels.
C. Cotton stalks have low calorific value which after being processed into particles will be greatly increased. They even can replace firewood, coal, fuel oil, liquefied petroleum gas and other fuels.
